I'm glad he said this is a problem with America and not just Texas. Zero tolerance is hurting kids with bringing scissors to school or handing Advil out for headaches. It's probably one of the most distructive policies we could ever have.
It's "zero responsibility": any administrator can simply point to the "zero tolerance" policy and claim to be following the established rules. It's entirely a CYA measure for staff, and has nothing to do with the well-being of students.
